IMPROVEMENT IN WATER-WHEELS.

Specification forming part of Letters Patent No. 166,004, dated July 27,1875; application filed June 26, 1875.

To all whom it may concern:

Be it known that I, HARVEY W. HAWLEY, of Walton, Delaware county, NewYork, have invented a new and Improved Water-Wheel, of which thefollowing is a specification:

Figure 1 represents a top view of my improved water-wheel, showing somebuckets in section. Fig. 2 is a vertical transverse section on the line0 0, Fig. l; and Fig. 3 is a perspective view of a bucket detached.

Similar letters of reference indicate corresponding parts.

My invention relates to an improved waterwheel, that may be used eitherin horizontal or vertical position with great effect, utilizing nearlythe whole head of water, and allowing the adjustment of the buckets todifferent angles to the wheel, if desired.

The invention consists of a water-wheel with central web and solid ordetachable buckets extending to equal distance and suitable anglestherefrom.

In the drawing, A represents a solid web of circular shape that formsthe central part of the wheel, which may either be used in hori zontalposition in the manner of a turbine, or in a vertical position as anovershot wheel. The buckets B are either cast in one piece with the webextending at equal width at each side of the same, or made detachable tobe adjusted by means of recesses a, with smaller side extensions a, intowhich the buckets B, provided with recessed side flanges b, areinserted. The buckets B are adjusted by wedge-pieces d to either side ofthe recesses a, so as to be set to the greater or smaller head of water,and are rigidly secured to the web by wedge keys 6, driven through therecessed flanges b of the buckets, and the recesses a of the web.

The water strikes against the outer curved and tapering edges of thebuckets, and passes then between the buckets toward the central part ofthe wheel. The central position of the web divides the buckets, so thatvirtually two wheels are furnished to which the water is conducted inthe horizontal position of the wheel from the flume by a surroundingcasing to be discharged at the top and bottom of the same.

The solid web dispenses with the obstruction to the Water-pressure byradial arms and other parts. In the vertical position, the twofoldaction of the Wheel is obtained in similar manner, and a largepercentage of the waterpower utilized.

The wheel may be made entirely of cast metal in a strong and durablemanner, and the buckets readily set by driving out the Wedge-keys,changing the position of the buckets by the side wedges, and reinsertingthe keys at the opposite side.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A water-wheel made of a central solid web, andbuckets extending at equal width to both sides of the same,substantially as specitied.

2. The combination, with the recessed web, of a detachable bucket, setby side wedges in position, and locked by lateral wedge-keys,substantially as specified.
